Re: [w3c/webcomponents] Disallow attachShadow(...) for some elements. (#110)

Is there by any chance a list with the disallowed elements *and* the reason for why they cannot hold a shadow tree? I understand that some elements already have browsers populate a shadow tree in them or they aren’t meant to have child content at all (e.g. `input`).

I’m particularly interested in why the `details` element is not allowed.
